Trump earlier announced that “I am prepared to veto, if necessary.” regarding the vote, adding that “The Southern Border is a National Security and Humanitarian Nightmare, but it can be easily fixed!”

A big National Emergency vote today by The United States Senate on Border Security & the Wall (which is already under major construction). I am prepared to veto, if necessary. The Southern Border is a National Security and Humanitarian Nightmare, but it can be easily fixed!

In a message to Rand Paul and other Republicans who are considering voting against the national emergency declaration, Trump said that GOP Senators “are overthinking” the situation.

Republican Senators are overthinking tomorrow’s vote on National Emergency. It is very simply Border Security/No Crime – Should not be thought of any other way. We have a MAJOR NATIONAL EMERGENCY at our Border and the People of our Country know it very well!

The GOP lawmakers who are likely to vote against Trump are Sens. Thom Tillis of North Carolina, Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky and, as of Wednesday, Sen. Mike Lee of Utah.

The Democrats need four Republican votes to rescind Trump’s emergency.
